Background: Vehicular or automobile emission constitutes a significant health injury to traffic policemen posted at thenumerous traffic junctions.
Aim and Objectives: Evaluating the spirometric lung function test parameters of traffic policemen posted in Gangtok town and to compare and measure the findings with general police personnel and also to study the effect of exposure to long-term automobile pollution.
Materials and Methods: In this study, after matching for anthropometric variables such as weight, height, and body mass index, 40 traffic policemen were taken as case and 40 general duty policemen were taken as control groups. The exclusion criteria were duly screened, and only those subject who fulfilled the inclusion criteria were included after which the spirometric pulmonary function tests (PFT) s evaluation was done. The indices measured in the study included (1) Forced vital capacity (FVC) (2) Forced expiratory volume in 1 s (FEV1) (3) FEV1/FVC ratio (4) Peak expiratory flow rate (PEFR) (5) Forced mid expiratory flow (FEF 2575%). Spirometric indices of the subjects and controls were statistically analyzed using the students t test and p value computed against the degree of freedom.
Results: The traffic policemen showed decline in various PFT indices as compared to controls in terms of FVC(L), FEV1 (L), FEV1/FVC, FEF 2575%, PEFR, although it was not statistically significant.
Conclusion: The traffic policemen working in Gangtok town had decreased PFT, although it was not statistically significant in this study. Even then, we strongly recommend for the adoption and practice of various preventive measure from vehicular pollution and conduction of further studies on larger samples.
